Help please. Geomety/Statics hw. Do you understand

a.If force F is to have a component along the u axis of Fu = 8.0 kN , determine the magnitude of F. (Figure 1)

b. Determine the magnitude of the component Fv along the v axis.

Fu = F cos 45
F = Fu/cos45 = 8/0.707 = 11.315 kN

then Fh = Fcos 45 = 11.315 x 0.707 = 8 kN This force is on a horizontal axis
So Fv = Fh cos60 = 8 x 0.5 = 4 kN

This looks hard too, maybe you should get a tutor.

a. F = 11.3KN
b. Fv = 7.7KN
